How to Harvest Red Leafy Lettuce

by Jenny Harrington

Frequent harvesting improves lettuce production.

Leaf lettuce provides a consistent supply of fresh greens since you can harvest it multiple times throughout the growing season. Leaf lettuce prefers cooler temperatures and grows as a fall, winter and spring crop in Sunset's Climate Zones 14 through 17. In mild summer areas, the slow-bolting red leafy types, such as Red Fire and Red Sails, may produce all summer. Harvesting red leafy lettuce properly doesn't damage the plant and encourages further growth.

1

Harvest the first set of leaves about 45 days after planting, when the outer leaves are about 6 inches or greater in length. Cut the outer leaves from the plant with a clean knife near their base.

2

Cut fresh outer leaves once or twice weekly, depending on how quickly the plant grows and replaces the foliage. Leave the interior foliage in place to continue growing and producing.

3

Remove the top third of the entire plant with the knife or shears once the plant reaches full size. Harvesting in this manner encourages a fresh flush of growth.

4

Harvest the entire plant before it bolts, usually before summer temperatures rise above 80 degrees Fahrenheit, but this depends on the variety. Cut off the plant at ground level with the clean knife.
